Oil fume detection system based on oil fume impact retention, balance loop and algorithm compensation

Abstract

The invention discloses an oil fume detection system based on oil fume impact retention, a balance loop and algorithm compensation; the oil fume detection system comprises an oil fume impact retentiontype detection probe; the oil fume impact retention type detection probe comprises a probe front section and a probe rear section which are mutually butted and communicated; a gas storage cavity is formed in the probe front section, the section of the gas storage cavity is of a rhombus structure, and lampblack entering the gas storage cavity through impact of a gas inlet is in a retention state along with flow guide impact of the inner cavity wall of the gas storage cavity. The system further comprises a smoke guide pipe, a balance box arranged on the smoke guide pipe in a communicating modeand a draught fan installed on the smoke exhaust pipe. Two ends of the smoke guide pipe are respectively communicated with a smoke exhaust pipe positioned at the front end of the fan to form a complete lampblack guide loop; and an algorithm compensation program is further included, and the detection numerical value of the oil smoke detector is compensated through the algorithm compensation programso as to reduce the defect that the oil smoke detection numerical value is small due to the negative pressure influence. The negative pressure influence can be greatly reduced, and the detection precision is improved.

Description

technical field [0001] The invention belongs to the technical field of oil fume detection, in particular to an oil fume detection system based on oil fume impact retention, balance circuit and algorithm compensation. Background technique [0002] In the oil fume detection process, it is necessary to use a fume detector for detection. The difficulty of oil fume detection is that the front end cannot detect data, and the data value is too small due to the influence of negative pressure. In addition, due to the unreasonable structural design of the detection probe of the existing oil fume detector, the oil fume goes straight in and out, resulting in a small (insufficient) amount of oil fume entering, which has a great impact on the progress of the precise measurement. In addition, the harsh environment in the smoke exhaust pipe will also cause relatively large impact damage to the detection probe, reduce the service life, and affect the detection accuracy.

[0002] In the oil fume detection process, it is necessary to use a fume detector for detection. The difficulty of oil fume detection is that the data cannot be detected at the front end, and the data value is too small due to the influence of negative pressure.

In addition, due to the unreasonable structural design of the detection probe of the existing oil fume detector, there is a phenomenon of straight in and out of the oil fume, resulting in a small (insufficient) amount of oil fume entering, which has a great impact on the progress of the precise measurement

In addition, the harsh environment in the exhaust pipe will also cause greater impact damage to the detection probe, reduce the service life, and affect the detection accuracy
